1. Shrinkage of the fabric The shrinkage of the fabric refers to the percent shrinkage of the fabric after washing or soaking. In general, the fabric with the largest shrinkage rate is synthetic fibers and their mixed textiles, followed by wool and linen fabrics, and the center of cotton fabrics has a large shrinkage, and the biggest ones are viscose fibers, rayon, and artificial wool fabrics. 2. The fabric shrinkage factors: 1 different raw materials fabric, the shrinkage rate is different. In general, fibers with high hygroscopicity swell after fiber soaking in water and increase in diameter, length, and shrinkage. For example, the viscose fiber has a water absorption rate as high as 13%, and the synthetic fiber fabric has poor hygroscopicity and its shrinkage rate is small. 2 Different fabrics have different densities and shrinkage rates. If the warp and weft density is similar, the warp and weft shrinkage is also close. After the density of the fabric, the warp shrinkage is large, on the contrary, the weft density is greater than the dense fabric, the weft shrinkage is also large. 3 The thickness of the fabric yarns is different, and the shrinkage rate is also different. The coarse cloth shrinkage of the yarn is large, and the fabric shrinkage of the fine yarn is small. 4 Different fabric production processes have different shrinkage rates. In general, in the process of weaving and dyeing, the fabric is stretched many times, the processing time is long, and the shrinkage of the fabric with greater tension is larger, and vice versa.
